80端口被占用怎么解决win10,端口80被占用

问题背景

使用vite将项目启动配置到80端口的时候发现80端口被占用。

通过浏览器访问该页面时显示 it works .响应头的Server中显示由apache提供服务

问题排查

通过端口命令查找占用端口的进程

sudo lsof -i:80COMMAND  PID USER   FD   TYPE             DEVICE SIZE/OFF NODE NAMEhttpd    145 root    4u  IPv6 0x86fb7c76ad702387      0t0  TCP *:http (LISTEN)httpd   1214 _www    4u  IPv6 0x86fb7c76ad702387      0t0  TCP *:http (LISTEN)httpd   3143 _www    4u  IPv6 0x86fb7c76ad702387      0t0  TCP *:http (LISTEN)httpd   3144 _www    4u  IPv6 0x86fb7c76ad702387      0t0  TCP *:http (LISTEN)httpd   3145 _www    4u  IPv6 0x86fb7c76ad702387      0t0  TCP *:http (LISTEN)

尝试通过命令停用服务释放端口占用显示该服务未启用

/opt/homebrew/opt/httpd/bin/httpd -k stopAH00558: httpd: Could not reliably determine the servers fully qualified domain name, using admindeMacBook-Pro-7.local. Set the ServerName directive globally to suppress this messagehttpd (pid 5691?) not running

查看apache的index.html路径并将文本内容改为 it ,访问本机环回地址仍显示it works 初步推断本地存在不止一个apache。

通过监视器查询与端口关联进程145获得信息父进程为launched用户为root。

由于该服务被kill掉以后会被立即重启因此需要从守护服务当中关闭掉该服务。

在守护进程相关目录下进行httpd服务查询。

与守护进程相关目录为

TypeLocationRun on behalf ofUser Agents~/Library/LaunchAgentsCurrently logged in userGlobal Agents/Library/LaunchAgentsCurrently logged in userGlobal Daemons/Library/LaunchDaemonsroot or the user specified with the key UserNameSystem Agents/System/Library/LaunchAgentsCurrently logged in userSystem Daemons/System/Library/LaunchDaemonsroot or the user specified with the key UserName

查找系统守护进程目录下的httpd服务并移除该服务。

/System/Library/LaunchDaemons sudo launchctl list  | grep httpd113440org.apache.httpd

查看该服务相关配置

cat org.apache.httpd.plist<?xml version1.0 encodingUTF-8?><!DOCTYPE plist PUBLIC -//Apple//DTD PLIST 1.0//EN  version1.0><dict><key>Disabled</key><true/><key>Label</key><string>org.apache.httpd</string><key>EnvironmentVariables</key><dict><key>XPC_SERVICES_UNAVAILABLE</key><string>1</string><key>OBJC_DISABLE_INITIALIZE_FORK_SAFETY</key><string>YES</string></dict><key>ProgramArguments</key><array><string>/usr/sbin/httpd-wrapper</string><string>-D</string><string>FOREGROUND</string></array><key>KeepAlive</key><true/></dict></plist>

删除掉该守护服务后80端口被释放。

/System/Library/LaunchDaemons sudo launchctl remove org.apache.httpd

至此问题解决。

问题结论

由于系统守护进程中包含了一个httpd服务,导致该服务会自启动并占用80端口。
